Question

C=85x+60 solve for x

Answer 1

C=85x+60
Subtract 60 from both sides and you get c-60=85x divide both side by 85 and get c-60 over 85=c

Answer 2

$C=85x+60$ 

$c-60=85x$       $\ Subtract \ 60 \ from \ both \ sides$ 

$\dfrac{c-60}{85} = x$        $\ Divide \ both \ sides \ by \ 85$ 

$x= \dfrac{c-60}{85}$
